Fatality Trends
Pedestrian Master Plan 2010 ▰ Vision: For Louisville to become the safest and most appealing community for pedestrians! ▰ Mission: Create a community wide culture that supports pedestrians through physical improvements, policies and pedestrian programs by increasing the pedestrian system network while simultaneously reducing the rate of pedestrian crashes.
Understanding Pedestrian Crashes ▰ 23% of fatalities occurring on Metro roadways were pedestrian fatalities. ▰ Louisville conducted a 5-year pedestrian crash analysis to identify: ▰ Trends ▰ High risk populations ▰ High crash locations

Vision Zero ▰ aka: Safe Systems Approach ▰ Principles: ▰ People make mistakes ▰ Crashes are going to happen ▰ The human body can only tolerate a certain amount of crash force
Vision Zero ▰ Why? ▰ Average Crash Costs in KY: ▰ Fatal Crash = $9,281,571 ▰ Serious Injury = $537,913 ▰ Societal Costs: ▰ US: $433.7 Billion (Source: National Safety Council) ▰ KY: $8.9 Billion
Vision Zero ▰ Paradigm Shift: ▰ Let’s not focus on eliminating crashes ▰ Let’s focus on eliminating fatalities and serious injuries
Vision Zero ▰ How? ▰ Other elements of the Safety Systems approach: ▰ We can’t continue to blame the driver ▰ Shared responsibility ▰ Proven solutions ▰ Proactive approach (treat the risk factors)
Shared Responsibility? ▰ The Swiss Cheese Model: ▰ Layered security measures are represented as slices of swiss cheese with the holes being weaknesses in the parts of the system ▰ A “failure” only results when a hole in each slice momentarily aligns, permitting a hazard to pass through The Swiss Cheese Model was originally put forward by Dante Orlandella and James T. all of the slices Reason of the University of Manchester
Vision Zero ▰ “Safe Systems” Goal: ▰ ensure redundancy in the system so that when a crash does happen, the crash forces released are within the boundaries of human tolerance and that no fatalities should occur and serious injuries are reduced Source: Roads and Traffic Authority of New South Wales
Vision Zero ▰ Treat the risk factors? ▰ Improve the roadway features with high correlation to fatal & serious injury crashes ▰ How are risk factors determined? ▰ In-depth Safety Diagnosis (aka Analysis of Crash & Roadway data) ▰ Engineering Judgement
